    Hi,

    Someone mentioned that there is Memory Leak issue with EventServer,and there is patch for this Memory Leak Bug.

    We are currently working on 6.7 with SP1.
    is this patch something we should have as a must.

    Can anyone shed some light on this.

    Thanks,
    Sai.

    Hi,

    We had to have the patch (an others) as it caused repeated crashes.

    You can test if you need it by repeated running the same test case, while running mon.sh (supplied by Ascential). If the memory usage goes up after every run, you have a leak which will eventually crash the system.

    If memory serves the leak was in the "On Errors an Warinings" audit option.

    Cheers,

    To test for memory leaks, run the same map(s) with the same data again and again, using mon.sh on UNIX to see if there is a growth. There must be no errors in the system, since the Event Server will show a memory increase as it stores the error information for the Management console. Also make sure that you are not unintentionally increasing the data size. One leak was reported when the first map did a "select * from tablename", and another map in the system was adding rows every run.

    For Windows, you need to watch the task manager, or set up Windows Performance monitor.

    There was an issue with one error, on warning or on error or warning if enabled in the audit log, but I think this was for 7.5.0 and fixed in 7.5.1. If you have 7.5.x you also need a patch for EC60894 if you use maps that connect to a database using an MDQ.

    Wait a while and upgrade to 8.0, there are so many new features it will be worth it.

    Contact your Account Exec. We may even have an opening for a few more beta customers.

    I think late 3rd quarter, but I am not in the group that determines release dates.

    We are in the process of testing 7.5.1 (we use 6.7.1 in production), and we use MDQ files extensively for our database access. In our initial tests we have been getting a -1001 error (Memory allocation error) from the DB adapter. Is the patch you mentioned (EC60894) for that issue? If so, sounds like I need to request it!

    I am monitoring the event server with some of the maps. Right after I refresh the service, the map were finishing within a second, and then they start dragging and keep going up to 10 to 15 seconds. I check the task manager to see if there is a memory leak, but it seems to be fine. Any Ideas?

    Myung,

    What version of ES on what platform? This is not a memory leak, but I bet it is a resource conflict or you are connecting to a DB and it is getting over worked, or something like that. Check your Management Console for init pendings, resource pendings etc. Is the Event Server Monitor tol. Make sure the Idle settings are in place for the adapter that require it. Make sure Maxthreads is not too high for your hardware.
